Abstract
The invention relates to a small-sized electric tapper, which is characterized in that an electric motor is connected with a base; the end of an electric motor shaft is provided with a rubber wheel which is arranged between the rims of a friction wheel; the friction wheel is arranged on a main shaft between bearing blocks; a bearing bush is arranged in the bearing block; the bearing blocks are connected with the base; one end of the main shaft is provided with stuck pot. An operation method of the small-sized electric tapper is as follows: 1) starting the electric motor to rotate at a speed of 1400r/min, aligning a hole on a workpiece with a screw tap, driving the workpiece to ensure friction between the rubber wheel and the rim I and tapping the screw tap; 2) when the depth of screw tap tapping is equivalent to the length of through processing, pulling out the workpiece backwards to ensure friction between the rubber wheel and the rim II, with friction force of 2-10kg, and withdrawing the screw tap. The electric tapper has the effects of simple structure, convenient use, long service life, high working efficiency and excellent quality of processed products, and also has the effects of good aligning accuracy and safety performance as the screw tap does not rotate before threading.
Description
Technical field
The present invention relates to the electric tools field, relate in particular to a kind of small-sized electric tapper that the metallic element tapping is used in the electrical installation project construction that is applied to.
Background technology
In the electrical installation project work progress, need the metallic element of processing more, in the limited duration, energy high efficiency, the high-quality processing tasks of finishing often be unable to do without the use of some electric tools in processing and making process.The tapping machine function of use of prior art is more single, uses dangerously, and working (machining) efficiency is lower, is not suitable for the requirement of electrical installation project job site.
Summary of the invention
The objective of the invention is in order to solve the deficiencies in the prior art part, a kind of simple in structure, high efficiency, small-sized electric tapper easy and safe to operate are provided.
For achieving the above object, the present invention realizes by the following technical solutions:
Small-sized electric tapper, it is characterized in that, motor is connected with base, the motor reel end is provided with the rubber wheel, rubber wheel is arranged between the friction pulley wheel rim, and friction pulley is arranged on the main shaft between the bearing block, is provided with bearing shell in the bearing block, bearing block is connected with base, and main shaft one end is provided with the card jar.
Described small-sized electric tapper, its method of operating comprise mantle fiber, move back silk, it is characterized in that:
1) starting motor, 1400 rev/mins of motors speed to going into screw tap, promote hole on the workpiece workpiece drive main shaft and move backward, and the rubber wheel rubs mutually with wheel rim one, and frictional force is at 5～30kg, and screw tap is shot.
2) shoot the degree of depth when screw tap and reach when passing through processing length, workpiece is extracted, after drive main shaft when pulling out and move forward, rubber wheel and wheel rim two-phase friction, frictional force is at 2～10kg, screw tap withdraws from, mantle fiber finishes.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is simple in structure, easy to use, long service life, has higher operating efficiency, and product processed is superior in quality, because screw tap does not change before the mantle fiber, so all very good to silk accuracy and security performance.

Among the figure: 1-main shaft 2-bearing block 3-friction pulley 4-motor 5-rubber wheel 6-card jar 7-silk vertebra 8-base 9-wheel rim one 10-wheel rim two 11-bearing shell 12-workpiece
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
See Fig. 1, small-sized electric tapper, motor 4 is connected with base 8, motor 4 shaft ends are provided with rubber wheel 5, rubber wheel 5 is arranged between friction pulley 3 wheel rims, and friction pulley 3 is arranged on the main shaft 1 between the bearing block 2, is provided with bearing shell 11 in the bearing block 2, bearing block 2 is connected with base 8, and main shaft 1 one ends are provided with card jar 6.
Small-sized electric tapper, its method of operating comprise mantle fiber, move back silk:
1) starting motor 4, and 1400 rev/mins of motors speed to going into screw tap 7, promote hole on the workpiece 12 workpiece 12 and drive main shafts 1 and move backward, and rubber wheel 5 rubs mutually with wheel rim 1, and frictional force is at 5～30kg, and screw tap 7 is shot.
2) shoot the degree of depth when screw tap 7 and reach when passing through processing length, workpiece 12 is extracted, after drive main shaft 1 when pulling out and move forward, rubber wheel 5 rubs mutually with wheel rim 2 10, frictional force is at 2～10kg, screw tap 7 withdraws from, the mantle fiber end.
See Fig. 2, during processing work 12, starting motor 4 drags 5 rotations of rubber wheel, operating personnel stand in main shaft silk vertebra 7 sides, to aim at main shaft screw tap 7 with workpiece 12 holes that bench drill processes, and promote workpiece 12 drive main shaft screw taps 7 and move backward, when the rubber of side contacts rotation in the wheel rim on the friction pulley 31 takes turns 5, because frictional force effect friction pulley 3 is just changeing with motor 4, carries out mantle fiber;
See Fig. 3, after mantle fiber put in place, pulling workpiece 12 interlock main shaft screw taps 7 moved forward, rubber wheel 5 counter-rotatings of side contacts rotation in the wheel rim 2 10 on the friction pulley 3, and workpiece 12 withdraws from, and mantle fiber finishes.
The present invention is simple in structure, easy to use, long service life, has higher operating efficiency, product processed is superior in quality, because screw tap 7 does not change before the mantle fiber, so it is all very good to silk accuracy and security performance, be specially adapted to the electrical installation project job site, before using base 8 fixed, just can be various work-piece tappings easily.
